IMPROVEMENT IN EXCELSIOR-MACHINES Specification forming part of LettersPatent No. 151,742, dated June 9, 1874; application filed February 6,1874.

To all ivhom it may concern:

Be it known that I, DEXTER S. BAILEY,

of Dover, in the county of Piscataquis and State of Maine, have inventedcertain new and useful Improvements in Excelsior-Machines; and I dohereby declare that the following is a full, clear, and exactdescription thereof, that will enable others skilled in the art to whichit appertains to make and use the same, reference being had to theaccompanying drawings and to the letters of reference marked thereon,which form a part of this specification, in which Figure 1 shows a sideelevation of my machine; Fig. 2, a detail of two of the sections andtheir uniting-joint Fig. 3, a perspective of the drum.

Same letters show like parts.

My invention aims at producing an excelsiormachine which shall performits work with the least possible waste of material and My deviceconsists of an endless chain composed of sections linked together,passing around and receiving its motion from drums, between whichitmoves, in a straight line, and carrying, inserted in mortises in saidsections, cutters of any proper construction for scoring the bolt andremoving the shav ing. The bolt isapplied to the cutters on the chain atthat point where their motion is rectilinear, and is' fed up to them byany of the ordinary set-works.

I will now proceed to describe my machine by reference to the drawing.

Figure 1, at a, shows the frame of the machine, having shafts b b ateach end, upon one extremity of which are pulleys c c for receiving thepower from the shafting of the mill, and upon the other drums d d forcommunieating motion to the endless cutter-carrying chain c, whichpasses around them. The chain is composed of sections f of any suitablematerial, mortised at g h, in one of which mortises, g, are securedscorers 'i, and in the other planers j. The sections are secured to eachother by metallic plates 70, extending behind the joint and turned overit at top and bottom, and rods lpassing through both plates andsections, so as to make a joint uponwhich the sections may turn .toaccommodate themselves to the periphery of the drums, said sectionsbeing placed sufficiently distant from each other and constructed toallow them to turn without interfering. These plates k effect twopurposes: Besides extending across the top and bottom of the joints,uniting the sections of the chain and serving as a bearing for'thepivot-rods 1, they pass behind the chain and serve to stiflen it whileoperating on the bolts, at the same time, from their construction,allowing it to pass freely around the drums d. The rods 1 projectthrough the plates k, at top and bottom, and are received innotches orindentations cut around the circumference of the drums at m, to preventany slip of the chain. The drums are recessed to receive that portion ofthe chain inside the line of the rods. At a is a table for the boltstorest upon while being cut, the sections having a rectilinear motionpast said table.

Ordinary set-works may be provided, but these are not shown in thedrawings.

Any number of bolts may be cut at one time, depending only upon thenumber of sections having a rectilinear motion at the same time, and thelength of the receiving-table n.

The drawing shows a machine capable of cutting six bolts- -three on eachside--the sides being counterparts one of the other.

The capacity may be increased by adding sections and separating thedrums d to accommodate them.

What I claim as my invention, and desire to secure by Letters Patent,is-

In an excelsior-machine, the combination of the drums or sprocket-wheelsd d with the endless cutter carryin g chain 6-, provided with thecutters j and t, and consisting of sections f united and stiffened byplates is, through which pass the pivot-rods Z, all operating andconstructed as shown and described.

In testimony that I claim the foregoing I have hereunto set my hand this30th day of January, 1874.
